Re: XSP problem/Cocoon1.7/tag-libs, how to..
Joseph, I confirm your results with cocoon 1.7.
I several other elements of informations. They helped me
solve the problem with Cocoon 1.7. Here they are.
- Stefano Mazzocchi confimed to me that XSP has a problem
in cocoon 1.7, which has now been fixed in CVS (supposedly
packaged with the 1.7.1 to be).
- Peter Moravek sent me his solution to the problem. I add some of my
observations to his material below:
With cocoon 1.7:
1/ use xalan_0_19_3D03.jar,
2/ make a directory where to hold the tag libraries, for instance /usr/local/cocoon/taglibs
put the XSP part of your style sheets there. (see below for an example).
3/ add this directory to the JServ engine classpath
4/ use the resource:/ way to point to the XSP .xsl file.
eg processor.xsp.library.example.java = resource://samplelib.xsl
5/ restart the jserv engine that serves cocoon (you need to restart after each
modification you make to a library: serious restriction at development time
in my opinion)
6/ touch sample.xml (the source) or clean the repository (there is a cache problem:
the page is not recompiled when a library changes, even when you kill and restart
the cocoon jserv engine! Now that's really not intuitive..).
7/ access sample.xml
When you develop, you need to go through steps 5-7 each time you make a change to the
library. Great fun!
Well, at least this is a work-around. I wonder if these cache problems will be solved in
cocoon 1.7.1.
